JOHN HOWARD MCELROY, OF CHICAGO, ILLINOIS.

VOTING-MACHINE.

Application filed April 29, 1908.

To all whom it may concern:

Be it known that I, Jenn How. in M- Fnnov, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Votingl\lachines, of which the following is a full, clear, and exact s11)ecitication.

My invention is concerned with voting machines of the type adapted for use in general elections, and comprises a novel interlocking mechanism adapted to be intercl'iangeably used for single-eainlidate and multi candidate to be elected groups, as occasion may demand; (2) a novel resetting mechanism, parts of which may be combined with the straight-ticket mechanism,when the latter is cn'iployed, thereby reducing the number of necessary parts; and, finally, certain novel features concerned with votingmechanisin generally.

To illustrate my invention, 1 annex hereto six sheets of drawings, in which the same reference characters are used to designate identical parts in all the figures, of which,*

Figure 1 is a front elevation of the upper portion of the machine, with a portion of the left-hand side in section just inside of thecasing, and with the right-hand side in section along the vertical plane of the interlocking sleeves; Fig. 1 is a similar view of the lower portion of the machine; Fig. 2 is a vertical section on the line 2- 2 of Fig. 1; Fig. 2" is a similar view on the line of Fig. 1; Fig. 3 a vertical section on the line 33 of Fig. 1; Fig. 3 is a similar view on the line 3-3 of Fig. P; Fig. 4 is an end elevation of a portion of the top of the machine, as seen from the right-hand side of Fig. 1; Figs. 5 and (3 are end and top plan views of one of the yes and no keys; Figs. 7 and 8 are a top plan view and side elevation of one of the straight-ticket keys; Fig. 9 is a detached view of a portion of the opc'aiting bars and i'nechanism shown in Fig. 2; Fig. 10 is a plan view in horizontal section on the line 10-10 of Fig. 1', Fig. 11 is a similar view on the line 11 11 of Fig. 1; Fig. 12 is a similar view on the line 12- 12 of Fig. 1; Fig. 13 is a similar view on the line 13-13 of Fig. 1 Fig. 1st. is a rear elevation of the registersupporting frame, with portions thereof broken out; Fig. 15 is a detail. of the same in section on the line 15-45 of Fig. 14; Fig. 16 is another Specification of Letters Patent.

In carrying out my invention, I prefer ably employ the generally rectangular casing, which is provided at its ends with the vertically disposed trough like end pieces and 31. These end pieces are connected by the various horizontal members, such as the trough-like casting 32, which is of the general shape of a channel bar, and which is used for supporting and adjusting the secondary interlocking elements, as may be desirable in arranging the registers for single or m1ilti-candidate-to-be-elected groups; the

small. angle-irons 33 and 3-1 near the top,

which have functions to be described; the heavy tube 35, which also serves to support the vertical bearing rods 36 for the primary interlocking elements; the heavy T-bar 3'7, with the angle iron 38 secured thereto, which T-bar serves as a support for the lower ends of the rods 36; the angle iron 39, which also serves as a support for the irregular-ballot writing-plate 4:0; and the heavy channel bar 41, which forms the bottom of the casing. There is a thin metallic top piece or covering and the rear wall 4t3 is made of sheet metal, and provided with the door at for giving access to the adjusting mechanism for the single or multi-candidate groups, which door is provided with one or more locks 4:5, the bolts of which cooperate with the angle iron 33; also the door 46, which gives access to the register frame in order to permit the reading of the totals, and which door is provided with one or more locks 17, the bolts of which conveniently oooperate with slots in the angle iron 33; and, linally, the door 48, which gives access to the irregular balloting mechanism, and which is provided with one or more locks 19, the bolts of which conveniently cooperate with the T-bar The front wall 50 is also constructed of sheet metal, and the top portion is flush with the outer surface of the end pieces 30 and 31, while its central portion is inset, so as to bring the keys 51 in the immediate vicinity of the interlocking sleeves 52 with which they cooperate in the manner to be described; and the lower portion of the front wall is located in a vertical plane about half way between the vertical planes of the top portion and the middle portion, and is snlliciently inset to furnish protection for the projecting lips of the irregular ballot slides 5%.

By the construction shown, it will be ap parent that the keys 51 and the projecting portions of the irregular ballot slides, as well as the bar 5t with which said slides cooperate, are located within the recess, as it were, formed between the end troughs or pieces 30 and 31, so that these parts are protected in a manner that they would not be if they projected beyond the general exterior of the machine.

The interlocking mechanism to prevent the simultaneous operation of more than the permissible number of keys in any ol'lice group is a modification of the interlocking mechanism shown in my application No. 358,815, tiled February 23, 1907. in that ap plication are shown thin, disk-like inter- .lcoking-members having surface. in three di'tferent planes, and inclined cam portions connecting the different portions, so that when adjacent disks are rotated in opposite directions, they will be separated by bringing the dilferent surfaces into engagement, thereby taking up any space that is allotted for the number of candidates to be voted for in the group. In that construction,the entire series of interlocking elements were arranged in one continuous row across the bottom of the machine, and this arrangement necessitated the connecting of these interlocking elements with the keys by straps of different lengths, according to the position of the row of keys to which the straps were connected. In my present construction, I provide a set of primary interlocking elements 52 for each otlice row of keys, and the end members of these primary interlocking elements cooperate with a transverse row of secondary interlocking elements each primary row moving its associated secondary interlocking element a distance proportional to the number of keys moved for operation in its primary row. By suitably securing the secondary interlocking elements in the position to which they would be moved by the operation of a single key in that primary row, all of the ollice rows may be employed for single-camlidateto-bc-elected groups, and by loosening the secondary interlocking elements, the various otlice rows may be thrown into groups permitting the operation of as many keys anywhere in the group as there are secondary interlocking elements loosened.

As shown in Figs. 1, 3, 15, 18, and 23, the primary interlocking elements 52 consist of elongated sleeves, which are preferably formed from sheet metal by first stamping out a blank, as shown in Fig. 17, which is subsequently formed into the sleeve form shown in Fig. 18, by means of suitable drawing dies. These sleeves have their ends formed with four eqiiii-distant surfaces 56 on the same plane, two equi-distant surfaces 57 on a plane above the four planes 5G, and two equi-distant surfaces 58 on a plane as far below the plane of the surfaces 56 as the plane of the surfaces 57 is above the plane of the surfaces 56. These surfaces 56, 57 and 58 are connected by the inclined cam surfaces 59, and the arrangement is such that when turned in their normal, unoperated positions, the ends of the sleeves nest in the ends of the adjacent sleeves, so that they take up a minimum of space. I may state that after the blanks have been rolled into the sleeve shape shown in Fig. 18, their ends are struck by dies, which serve to insure all of the ends being of uniform formation. All the eight essential sleeves 52 for each office group (there being seven sleeves for the regular candidate keys, if that many are provided for by law, and one sleeve for the irregular balloting mechanism of the group) are mounted to slide and rotate upon the bearing rod 36. the lower end of which is secured to the T-bar 37, as by the nuts (30 cooperating with the threaded end of the rod, and the upper end of which is secured to the tube 35, being passed therethrongh, and held in place by the nuts (31 cooperating with the threaded end of the rod. The various rods 33 are spaced apart an equal. distance, and the keys 51 are-mounted to rotate about the rods 36 as an axis, being provided with the central apertures (32 of the proper diameter so that the sleeves 52, which slide and rotate on the rods 36, will be free to slide in the keys 51, but are held from rotation therein by reason of the spline 63, which cooperates with the recess 64 in the key, and with the slot 65 in the sleeve. This spline G3 has the vertical portion cooperating with the slot (35 and the recess 6%, and the horizontal end pieces projecting slightly beyond the recess (it so as to prevent the key, spline and sleeve being separated after they are once assembled upon the rod 36. The keys 51 are also supported and held from vertical movement by reason of the ends (36 passing through the slots 67 in the front 50 of the casing. and it llt will be noted, especially from Fig. 12, that the ends 66 of the alternate rows of keys are directed in the opposite direction, the pointed ends of the keys extending down over the name of the candidate on the ballot to which the key is devoted, when the key has been moved to operative position. The end of the key thus serves 2 s a pointer or index to emphasize the location of the name of the candidate with which the key is associated, and it will be understood that the ends of the alternate rows of keys are pointed in the opposite directions for the reason that the sleeves must be rotated in alternate directions for simplicity in struc ture. The keys are also provided with the curved portions (38, which are struck on an arc of sufficient radius so that the surface will project into the slot 67 and prevent any implement being inserted into the casing through the slots. The rear end of the key is provided with the portion 69, which passes through the slots 70 in the straightticket and resetting bars 71. These portions 9 have their edges curved on the arcs of small circles, as shown, so that these portions of the keys will cooperate with the straight edges of the recesses 70 in whatever angle the key may be swung through, it being understood that the keys are swung tlnrmigh a angle of forty-five degrees at each operation, where the sleeves have the eight surfaces 56, 57 and 58 at each end. The portions (39 of the keys pass not only through the slots 70 in the resetting bars 71, but they also pass through slots 72 in the vertical. plate 73, which extends between the end pieces 30 and 31, being secured thereto in any suitable manner. As this vertical plate 73 is of thin metal, I preferably increase its rigidity by securing to it the strips 74: at suitable intervals extending across the machine and connected to the end pieces 30 and 31,. The top of this plate 73 is secured to the angle iron 75, which extends across the machine and is secured to the end pieces 30 and 31, and the bottom of this plate is secured to the angle bar 38, which in turn is secured to the T-bar 37,

lly reason of the keys being journaled, as it were, on the rods 36, and held from verti *al movement by the slots 9 and 72, it will be apparent that the keys can be swung througl'i the forty-five degrees permitted to each. As each key is swung from its normal unoperated position to its operated position, it rotates the sleeve 52, which it embraces, with it, and the action of the cam surfaces on the end of the sleeve with the cam surfaces on the top of the sleeve below and the bottom of the sleeve above, serves to lengthen the column of sleeves by the unit distance for each operated key. The slots are employed so that the :leeves, and especially the top ones, may

be raised as many unit distances as the number of keys in the group will permit. For instance, if the particularcolumn of keys under consideration were in a multi-candi- (lflttO-l)6%%lt0t( group where at least eight candidates were to be elected, it might happen that each one of the sleeves in that gz roup was rotated, the lowermost one by the irregular ballot mechanism, and the seven upper ones by reason of the regular party 'andidate keys being operated. This would necessitate the lowermost sleeve hav ing a raising effect of one unit, and the uppermost sleeve would have a raising effect of eight units. In order to reduce the friction of these sleeves 52 on the rods, I preferably make their internal diameter somewhat larger than the diameter of the rod 36, and form three bearing surfaces 7 G on the inner faces of the sleeves at the top and bottom by striking depressions 77 into the exterior of the sleeves, producing the corresponding bearing surfaces 76 on the interior of the sleeves.

The expanding effect of the operation of the keys in the office column is transmitted to the secondary interlocking mechanism by means of a non-rotating sleeve 78, which is provided with the similar cam surfaces on its lower edge, and which is provided with a vertical slot 79, through which passes a pin '80 secured in the rod 36, so as to prevent the turning of the sleeve on the rod while not interfering with. its upward movement thereon. Above this sleeve 78 is another sleeve 81, which might, in fact, be a continuation of the sleeve 7 8 as the two sleeves might be consolidated. This sleeve 81 is similar to the sleeve 78, in that it has the slot 79, by which it is similarly held from D'lOVBlHGllt, but its lower end may be plain to cooperate with the plain upper end of the sleeve 78. The top of the sleeve 81 is preferably provided with the arms 82, which may be struck out of the body of the metal, and which extend into the plane of the lugs 83 on the franchise-hunting elements 84:, the construction and operation of which will be explained further on. The top of the sleeve 81 cooperates with the tubular lower end 85 of the rack bar 86, and it will be understood that the tubular lower end of the rack bar slides on the rod 36 as a bearing, and I preferably form another hearing by smoothing off the surface of the tube 35 on each side, and forming the vertical slots 87 in the bodies of the rack bars, and I pass a shoulderedscrew 88 through each of the rods 87 and into the flattened surface of the heavy tube This additional bearing serves to overcome any tend ency of the rack bar to be thrust away from the cooperating teeth of the secondary 1nterlocking element. The edges of the rack bars or plates 86 abut against each other,

and they are provided with teeth 89, extending across the top thereof, and they are normally held downward by' the tension of the helicall'y-coiled contractile springs 90, which are secured to the lugs 91 at the tops of the rack bars, and the lower ends of the springs 90 of the rack bars on the rear are secured to the angle iron 34, while the lower ends of the springs 90 for the other rack bars are secured to the strip 92, which is placed across the front of the machine between the end pieces 30 and 31 for this purpose. The teeth 89 of these rack bars 86 mesh with the teeth 93 of the secondary interlocking sleeves 94c, which, like the primary sleeves, have cam surfaces at their ends, and are adapted to be retated in alternate directions, but instead of being rotated through a certain distance at each operation, as are the primary elements, they are arranged to be rotated through varying angles, depending upon how many keys have been operated in that associated column. I have shown the sleeves 9&- as designed to be rotated through an angle of ninety degress when all eight of the primary sleeves in their associated column have been operated, and to be rotated through only one-eighth of that angle when one primary sleeve has been operated, and so on throughout.

In Figs. 1 and 10, which represent the sleeves 93 in the position they would assume when one key had been operated in each group, or in the position they would be sesecured when they are arranged in singlecandidate-to-be-elected groups, it will be seen that there is no play between the sleeves, as they fit snugly against each other. If they be unloosened, so as to throw them in a multicandidate-to-be-elected group, and if none of the keys in the group be operated, the springs 90 will rotate them in the proper direction so as to produce a certain amount of lost motion or space between the sleeves. That is to say, the sleeves are not quite long enough to entirely till up the space which they occupy on the rod 95 upon which they are strung. If any one of these sleeves lll be rotated through a peripheral distance corresponding to the amount that the primary column is raised by the swinging of one of the sleeves the expanding action due to the shape of its cam edges will take up the lost motion which belongs to that particular sleeve, and if the adjacent sleeves 91- are held from movement, it cannot be rotated any further. If, however, there are eight sleeves in the multi-candidate-to-be-elected group, so that they are free not only to rotate, butto slide longitudinally upon the supporting rod 95, the sleeve being operated can be rotated through a total angular distance of ninety degrees.

the sleeves on either side thereof a su'llicient distance to take up the lost motion permitted in the group, and when this sleeve has been rotated the full ninety degrees, no other sleeve in the group can be rotated at all. Of, course, it will likewise be obvious that each sleeve in the group may be rotated through one-eighth of ninety degrees, or two sleeves can be rotated through forty-five degrees each, or any other possible combination, so that, as a result, any eight of the total number of sixty-four primary sleeves in the group can be operated by their keys, but no more. The fact that the rack bars 86 have teeth across the entire face thereof, and that these teeth will. be in engagement with the teeth 93 of the sleeves ST in any position to which they can be adjusted, insures the proper action of the secondary interlocking mechanism under any operation of the keys that may take place. This mechanism gives a very flexible arrangement, and one that enables me to put any number of primary sleeves 52 in a group that is ever required in actual practice. The proportions of the sleeves 94, shown enable me to place, say, thirty columns in a single group, and if it is desired to place more in a group, it is only necessary to decrease the pitch of the cam ends of the sleeves 9i proportionately, making it, say one half as great as illustrated, if it is desired to put twice as many columns of keys in a group.

The grouping of the sleeves 9-l is very readily controlled by means of the screws 96, which have the large milled portion, and the reduced portion which passes through the unthreaded apertures 97 in the bottom of the channel bar The screws 96 have the shoulder 98, which controls their position in the channel, and between the lower threaded end and the portion that extends through the apertures J7 is the shoulder 95), which determines the position to which the sleeves ll-Ll can be drawn by the screws, which, it will be understood, are screwed into the lTll1'32HlUl apertures 100 in the tops of the sleeves ill, which apertures are so located that the sleeves must be in the postion in which they would be moved by the operation of one key in their respective party columns before the screw can be put in place. It will be readily understood that the channel bar 32 in effect supports the sleeves 94, so that the rod 95 can be made small in diameter, if desired, thus reducing the friction of the sleeves when they are rotated. hen it is desired to form a multi-candidateto-be-elected group, all that is necessary is to unscrew the screws 96 of the sleeves 94- of the columns of keys which are to be included in the group. To prevent the possi- I bility of the screws 96 being mislaid, I prefduring which rotation 1t will have shoved l erably secure them in the machine by a cord 101, which extends between a pair of eyes 102 secured near the ends of the machine to the rear of the channel 32, and also through corresponding eyes 103 located between the screws. The reduced portions of the heads of the screws pass through 8- shaped eyes, one loop of which surrounds the key, while the cord passes through the other loop, and the slack in the cord is sufficient to permit one key to be unscrewed at a time. hen the key has been unscrewed, I preferably invert it, and to hold it in position I employ an extension 10 1 on the top, which is of the proper size to set into the aperture 97 from which'the screw has been removed. It will be understood that the sleeves 94: may be of any desired construction to effect the result shown, and I have shown them as having a hub portion of substantially the length equal to the distance between pairs of the rods The cam surfaces, of course, are narrow at one end, and wide at the other.

The frauchise-limiting 1'1'1GCl12111lS111 is best shown in Figs. 1, 2, 3, =1 and 11, where it will be seen to consist of the handle 105, which is provided with a plurality of pins 100, preferably six, projecting from its inner face and adapted to cooperate with six equi-distant and equal sized apertures in the end wall of the casing. The handle is provided with an index or pointer 10?, which .is adapted to point to the designations 108 of the various franchises. I have shown the machine as arranged for use at a primary election where the parties hold their primary on the same day, and the machine is labeled, in Fig. 1, as adapted for a primary in which the Republican, Democrat, Labor, Populist, Prohibitionist and Socialist: parties take part, and it will be understood that a certain section, say ten groups in a sixtykey machine, is given over to each party for the purposes of the primary election. When a Republican voter, for instance, comes to vote at the primary, the handle 105 is turned until the pointer 10? is to ard the word Republican, in which position the shaft- 1.09 is pushed in by the handle 105 to the position shown in Fig. 1. The handle 105 is secured on this shaft 109, which is provided with suitable collars to limit the distance to which it can be pulled out for resetting purposes, as hereinafter described. It is provided at each end with the similar rectangular l'iearing blocks 110 and 111, the bearing block 110 being at the other end from the handle 105, and sliding in ways 1.12 projecting inward from the end piece 530, while the bearing block 111 slides in corresponding ways in the other end piece The blocks are held in any suitable manner from rotation with the shaft 73, but, of course, must move longitudinally with said shaft, and are held from turning by reason of their rectangular shape cooperat-ii'ig with the w s. As seen in Fig. 11, each block is provided at the top and bottom with the cam slots 113, with which cooperate pins 111 projecting thereinto from the guide ways 112. These cam slots are preferably provided both on the, top and bottom of the bearings, and, with this construction, it will be perfectly apparent that as the shaft 100 is pulled out to reset the franchise-1imiting mechanism, it will be moved bodily to the rear of the machine an equal distance, thereby carrying the arms of the limiting elements 84 of which there is one for each column of keys, out of engagement with the lugs 82 previously referred to as formed on the upper ends of the sleeves 81. These franchise-limiting elements 81 are provided with the preferably radial arms 85, which are one less in numher than the positions to which the shaft can be adjusted. I have, for convenience, indicated six positions of adjustment and five of these arms or lugs 83. These lugs 83 are spaced apart an equal distance, except that one of them is omitted, as it were, and this enables me to make any desired adjustment of these franchise-limiting elements upon the shaft 109, which preferably has the equi-angular cross section shown between the end pieces 30 and 81, with as many angles as there are adjustments for the shaft. By stringing these elements 81 upon the shaft in any desired arrangement, and securing them at the ends, as by the bearing blocks 110, it will be perfectly apparent that I can arrange it for any desired franchise limitation that may be necessary. As is indicated in Fig. 3, when the door 40 is opened and the set screw 115, which holds the two parts of the shaft 109 together, is removed, I can remove the major portion of the shaft 109 and the franchiselimiting elements strung thereon, as may be i'iecessary for ire-arranging them. The ways 112 are provided with the lugs 116 at their inner ends facing each other, and intended to cooperate with the arms 83 of the end elements 84, to assist in preventing the rotation of the shaft 109 in case an effort is made to vote for more ofiicers or individuals than the voters franchise allows. Of course, it will be understood that when a change in the groupii'ig of the machine is to be made, the door 44. is opened, and access is given to the screws 00 for making any necessary adjustment.

As is seen in Figs. 5, 6, 22 and 23, the inner ends of the keys 51 are generally of an arc shape, and are provided with a tooth or spur 117 at one end of the arc-shaped portion, and with a locking surface 118 which is curved on the are of a. circle with the axis of the rod 30 as a center, and between the tooth 117 and the locking surface 118 is a recess 119. These parts are intended to engage with the primary element of the register-wheel train, which I preferably connect to a carrying pinion 120, which is similar to the carrying pinions 121 and 122 which serve to carry from the units wheel 123 to the tens wheel 12%, and from the tens wheel to the hundreds wheel 125. As these carrying pinions are customarily made of a comparatively soft composition used in making what are known as finished castings, I do not have the key, which is stamped from sheet metal, and consequently hard, cooperate directly with the pinion 120, but secure on this pinion an actuating member 126, which, as seen in Fig. 21, consists of adisk-shaped portion having the four arms 127 turned up from the sides thereof and provided with the star-shaped aperture 128 adapted to fit over the four teeth constituting the upper portion of the carrying pinion 120 upon which itis placed. It will be understood that this member 126 is first blanked out of sheet metal, and the arms 127 are then turned up into a vertical position. The position of the key and the carrying pinion when the key is unoperated is shown in Fig. where it will be seen that the tooth 117 rests between two of the vertical arms 127. Of course, it will be understood that the carrying pinions 120, 121 and 122 are strung on a vertical shaft 128, and that the units, tens and hundreds wheels, 123, 12% and 125, are strung on the shaft 129. Suppose now the key is swung from the position shown in Fig. to that shown in Fig. 23. As the key is turned, the tooth 11'7 bearing against the arm 127 rotates the pinion 120, the succeeding arm 127 in that case passing into the recess 115). When the pinion 120 has been rotated through ninety degrees, the locking surface 118 comes in engagement with the adjacent pair of arms 127, and locks the pinion from further movement. I may at this point state that when a voter is in the machine, and it is ready for operation, the frame carrying the register wheels is in position so that the teeth 117 can engage the arms 127 to operate the machine. lVhen the voter leaves the booth, the register frame is first moved to the rear far enough to disengage the operating teeth 117 from the arms 127, and while the frame is in this position, the keys are moved back to their normal unoperated position by the movement of the bars 71, by the reset-ting mechanism to be described. After the keys have been reset, and are held in that reset position, the register frame is then moved back to normal position, and consequently the teeth 117 engage between the arms 127 that are now nearest the key. Of course, it will be understood that if a key has been operated by the voter, as shown in Fig. 23, and he desires to change his vote, all that he has to do is to throw the key back to its unoperated position. when the engagement of the tooth 117 with the arms 127 which it has just passed in the setting operation, will unoperate the register. Of course, it will be understood that the carrying pinion 120 has on its lower half a certain number, say eight, teeth, which engage the continuous row of pins 130, which project upward from the top of each of the wheels. The under side of each of the wheels is provided with the pair of downwardly projecting pins 131 between which is the notch 132, and the parts are so arranged that two of the four long teeth on the carrying pinion cooperating with the periphery of the wheel of lower denomina tion, locks the pinion from operation until the recess 132 is reached, when the movement of the wheel of lower denomination from 9 to 0 will, by the engagement of the pins 131 with the intermediate one of the short teeth, rotate the carrying pinion through ninety degrees. and it, of course, will carry the wheel of higher denomination, by reason of the engagement of its teeth with the pins 130 projecting upward from the periphery of said wheel of higher denomination.

The shafts or rods 128 are rigidly secured in the register frame made up of the vertical end pieces 133 and 134., which are connected by the horizontal cross pieces 1.35 between each row of registers. The register frame also has, at the opposite end from the bar 13 3, another bar 136, and projecting ont wardly from the end pieces 133 and 13(3 are the pair of pins 137 and 1 38, which are pivoted in the swinging lower ends of the pairs of suspending links 139 and 140, the position of which indi fillttl in dotted lines in Figs. 2 and and which are pivoted at their upper ends upon pins projecting inwardly from the end pieces 30 and 31. The operating bars 14-11 and 142, to be more fully described hereinafter, are provided with the pairs of slots 1.1-3 and 141, which, as seen in Figs. and 2, are provided with the cam portions located about midway of their length, so that as the bars 141 and 142 are raised by the means to be described, the register frame will he swung to the rear :1 sufiieient distance to disengage the registers from the operating keys. \Vhen the bars 1+t1 and 142 are returned, of course, the reverse action takes place, and the registers are engaged with the keys, which are now in their unoperated position. To reset all the registers in the machine at a single operation, I arrange to move all of the register wheels proper out of engagement with the carrying pinions and to then simultaneously rotate all the shafts 12!) until the register wheels are reset. For this purpose, instead of mounting the shafts 12$) directly in the plates 135, I pass them through slightly elongated slots 145 in said plates, and also pass them through cam slots 116 which are placed in a number of auxiliary plates 11?, which are mounted to slide in bearings formed on the under sides of such plates 135 as they are next to, as I preferably employ only one-half as many of the plates 117 as of the plates 135. The guides for these plates 1 17 are conveniently constructed by securing straps 118 on the under sides of the plates 135. Each of the plates 1147 has the recess 1-15) in one end thereof, and a vertical, eccentric shaft 150 passes through all of these recesses and is secured in the arms 151 pivoted at the top and bottom of the frame. The upper arm 151 has secured thereon, above the top piece 152 of the frame, an arm 153, which is preferably provided with a set screw 1. so that it can be secured in different positions. Vhen the register wheels are in their normal positions, the plates 147 are in the position shown in Figs. 15 and 1G, and the screw 154- is adjusted to hold them in this position. \Vhen the registers are to be reset, the arm 153 is turned so that the plates 1-17 are drawn to the left as far as the slots 116 will permit their movement, and as they are thus moved, the cam surfaces of the slots will mov all the shafts 12.) to the rear of the machine as far as the slots 145 will permit. This separates the register wheels from the *arrying pinions and brings the pins 131 on all of the wheels into the plane of the pins 155, which project inward from suitable metallic strips 15c secured on the inner face of the glass plate 157 which forms the rear face of the register frame, and through which the readings of the registers can be taken without giving access to the wheels, to prevent any possible manipulation. Owing to the fact that the registers in the alternate horizontal rows must be retated in opposite directions on account of the different direction of movement of the keys, the pins 155 of the alternate rows are in the position shown in Fig. 20, while in the other rows they would be on the other side of the pins 131 from where they are shown. The. head of the lowermost or hundreds wheel 125 rests on a collar 158, and I preferably interpose very thin collars 15%) between the units and tens and the tens and hundreds wheels, and to insure the w eels turning with tie shaft 12!), I preferably flatten these shafts on one side, as shown, and make the apertures in the collars 158 and 15?) of the same shape, so that the collars must turn with the shaft 129. As the entire weight of the register wheels rests on these collars, it will be obvious that when the shafts 129 are turned with the wheels freed from the carrying pinions, the wheels will turn with the shaft until the dowm aidly-projecting pins 131 on each wheel strike the inwardly-projecting pins 155, when the movement of the wheels will be stopped.

With this arrangement, it will be obvious that when the shafts 129 are given a complete rotation all the wheels will have the same reading, which, however, will not be zero. The handle 153 is then turned back far enough toward its original position to a point which will be indicated by a recess for the set screw 151, in which the pins 131 are just out of the plane of the pins 155, and in which the arms 12? have not been brought back into the plane of the teeth 117. At

, this point, the rotation of the shafts 12$) is continued until all the wheels show Zero at the reading point, when the rotation of the shafts 12S) stopped and the arm 153 is swung back to its original position, in which the wheels are in engagement with their carrying pinions. As a convenient means for simultaneously rotating all of these shafts 129, I employ the mechanism best shown in Figs. 3, 13, 1-11 and 15, where it will be seen that I journal a screw shaft 160 in bearing brackets 161 which are carried by the lower ends of the shafts 129. These same bearing brackets 161, in addition to furnishing bearings for the screw shaft 160, have the vertical bearings 162 for the lower ends of the shafts 129, and beneath the bearings 162 I secure to these shafts the worm gear wheels 1655, with which the screw or worm 160 meshes. To turn the worm 160, I secure on one end thereof the milled end 161, which is preferably provided with the apertures 165, in which a wrench can be inserted in order to apply power more advantageously. It will be evident that as this worm shaft 160 is rotated, it will slowly rotate the worm wheels 163, which in turn will rotate the shafts 129, and that at a rate of speed slow that it will be impossible to get up sutlicient momentum so that the wheels will be advanced independently of the movement of the shafts 129.

To operate the machine when the voter leaves the booth, to finally fix the registration and return the parts to their normal position, I employ the horizontal shaft 166 journaled in bearings formed in the top of the machine in the end pieces and 31, and to this shaft may be secured a swinging bail and curtain. This shaft has secured thereto at each end, inside of the end pieces 30 and. 31, between them and the end plates 167 and 168, the 111119} 169, which have pins 170 projecting into the horizontal slots 171 formed in tlie top of the bars 141 and 142. These bars are mounted to slide vertically the distance that they will be moved by swinging the shaft 166 through an angle of ninety degrees, or, as shown, from the full-line to the dotted-line position of Fig. 2. As a convenient and simple bearing for these bars 1:11 and 1.42, I provide the bearing surfaces 172 and 173 at the top and toward the bottom of the end pieces 30 and 31. and pass the set screws 175 and 178 through the slots 17? and 178 formed in the bars 111 and 142. The bar 142 must have therein the slot 179 with the offset 160 at the bottom thereof, through which passes the outer portion of the shaft 109. as seen in Fig. 11. This slot 179 and the offset 180 are shown in the bar 111, although they are not necessary therein, but are merely shown for uniformity in design. The offset 180 is to permit the movement of the shaft 109 to the rear when the franchise mechanism is being readjusted, and it will be understood that the end plate 168 is provided with a short horizontal slot 181, indicated in dotted lines in Fig. 1, which slot is always covered by the disk or handle 105. Each of these bars 111 and 1 12 is provided with the outwardlyprojecting flange 182, and, as will be seen in Fig. 1, these flanges are provided with the cam slots 183, the slots being alternated or staggered, as the resetting bars 71 in alternate rows must be moved in the opposite directions, owing to the fact that the keys in alternate rows are swung in the opposite direction from inoperative to operative position. The bars 71 are preferably reinforced and thickened at their ends, which ends pass through suitable apertures in the end pieces 30 and 31, and are provided at one end with the pins 1st which project into the cam slots 183. As seen in Fig. 1, the top portion of these slots is of sufiicient width so that the bars T1 can be moved in the proper direction a sutlicient distance to set all the keys in any horizontal row in position for a straightparty vote, and, for this purpose, I provide the straight-party keys 185. which are shown detached in Figs. 7 and 8. It will be seen that these keys consist of the main portion, in which is located the bearing aperture 186 by which they are strung on the left-hand rod 36, and they are supported horizontally in slots in the front plate and the intermediate plate 713, which slots correspond to the slots 39 and 72, except that they are larger on account of the larger size of the straight-ticket keys. These straightticket keys have the surfaces 18?, corresponding to the surfaces 68 on the candidate keys, to fill the recesses through which they pass in the front plate 50 in all positions to which the key can be turned to prevent any implement being inserted. They also have the rear projection 188, which is curved on the arc of a circle, and takes into an aperture 189 of the same width in the bars T1, so that when the straight-ticket key is swung from the position shown in full lines in Fig. 12 to that shown in dotted lines in Fig. 12,

its corresponding bar 71 engaging with the extensions (39 of the candidate keys, will swing all said keys to operative position. The outer ends. 189 of the keys are preferably removable, and normally held in place by the screws 190. so thatwhen the machine is being shipped there will be no part of it projecting beyond the end pieces 30 and 31.

It will be understood, of course, that the wide tops of the cam slots 183 are provided so that the straight-ticket keys can be manipulated to move the bars 71 without interference, and it will be seen, of course, that the straight-ticket keys of the alternate rows must be moved in opposite directions. \Vhen the bars 111 and 1&2 are raised, the am slots have no effect on the bars 71 during the first part of the movement and while the register frame is being moved to carry the registers out of engagement with the keys. Toward the latter end of the movement, however, the cam surface 191 comes into engagement with its corresponding pin 18st and draws its particular bar 71 outward to its full limit, and holds it locked in that position by the narrow, vertical lower end of the cam slot so long as the curtain is raised and the machine open. The movement of this bar to this limited position by reason of the ends of the slots TO acting on the portion 69 of the candidate keys will move all said candidate keys to their unoperated position and lock them there until the curtain is lowered, when the parts will be restored to the position shown in Fig. 1, ready for another op eration.

To prevent any attempt to manipulate the machine by partial movements, I provide on one or both of the bars 141 and 1 12 the set of teeth 192, which cooperate with the spring-held dog 193 in the customary manner to cause a complete stroke of the bars in both directions.

The irre ular-ballot mechanism is best shown in Figs. 1, 2, 3, 9 and 18, where it will be seen that I provide the supply roller 19-1, which is journaled in suitable bearings in the end pieces 30 and At a suitable distance above this supply roller 19st, I journal the storage roller 195, and this roller is provided with the shaft 190, which is journaled in the bearings 19? formed in the end pieces 30 and 31, the projections for which are preferably recessed, as seen at 198, to accommodate one end of the helically-coiled expanding-s )ring 199, which is interposed between the bottom of the recess and the ratchctcd disk 200, which is splincd on the shaft 196. The teeth of this ratcheted disk 200, of which there is preferably one on each end, are normally out of the plane of the teeth 201, which are formed on the extension 202 of the bars 1 11 and 142. The ratcheted disks 200 are adapted to be moved inward against the tension of. the springs 109 to bring them into the plane of the teeth 201 when an irregular ballot has been indicated on the machine by mechanism to be de scribed, and it will be understood. that as the bars 141. and lei-2 are raised, if the ratcheted disks 200 have been moved into the plane of the teeth 201, the storage roller 195 will be rotated a suflicient distance to draw a suiticient supply of the paper 203 from the supply roll 104: to the storage roll 105. The paper, of course, passes over the writing plate 140.

The front of the casing is provided, in line with each of the party columns, with the elongated, rectangular recesses 20 1, which are normally closed by the solid portions 205 of the free balloting plates The operating projection of each plate projects through the top of the corresponding slot 204, and above the projection 53 is a recess 200, which. may be brought into register with the recess 204; by shoving down the irregular-ballot plate 5% to the position shown in dotted lines in Fig. 3 1V hen the irregular-balloting plate is thus moved down to uncover the paper sheet 203, it accomplishes several things. In the first place, an extension, or, more strictly, the upper portion 207 of the irregular-ballot plate is provided with the cam slot 208, best shown in Fig. l and into this cam slot 208 projects the rounded end 205) of a member 210, which corresponds in some of its functions to the keys 51. Like the keys 51, it is mounted at its front end in slots 211 in a plate 212 secured at the front end of the T-bar 37, for the purpose of supporting the inner ends of these members 210. Their rear ends 213, which correspond with. the portion (59 of the keys, cooperate with the slots-21 1 in the resetting bar 71 devoted to the irregru 1arballoting mechanism, and likewise through slots in the rear walls 73 corre sponding to the slots 72 through which the portions 09 of the keys pass. When the irregular-balloting slide is pulled down, the cam edge of the slot 208 swings the member 210 through an angle of fortyfive degrees, just as a key is swung, and this member is connected to its sleeve 52, the lowermost one in the series, by the slot and spline connection, just as the candidate keys are attached to their sleeves 52. The bottom of this lower most sleeve has the cam surfaces and cooperates with corresponding surfaces formed on the short sleeve 215 secured to the rod 86 above the horizontal flange of the T-bar S7, and its upper end has the corresponding cams cooperating with the intermediate sleeve 210, which has the cam ends, the same as the regular sleeves 52, but which is held from rotation by means of the pin 217 secured in the rod 36 and cooperating with the vertical slot 218 in said sleeve. Of course, it will be understod that the sleeve 52 might be lengthened until it extended up to the sleeve 52 of the lowermost regular key, in which case the intermediate sleeve 210 could be omitted. It will be apparent that, owing to the width of the cam slot 208 at the bottom, if the voter should attempt to beat the machine by voting for an irregular candidate in a single-candidate-to-be-elected column, and then returning the slide, and attempting to vote a regular-candidate key, he would be prevented, for the reason that the mere returning of the irregular-ballot slide does not turn back its sleeve 52 to release the interlock. These interlockii'ig sleeves are only returned when the machine is reset.

Toward the end of the downward movement of the free-balloting plate, the projection strikes the bar 55, which extends across the front of the machine, and the ends of which extend into the end pieces 30 and 31 through the slots 220 therein. As seen in Fig. 13, the ends of the bar 55 are turned inward and are secured to the vertically reciprocating bars 221, which, as best seen in Fig. 2 are mounted to slide in the bearings 222 and 223 formed or secured on the end pieces 30 and 31. These bars 221 have secured thereto and projecting inwardly therefrom the cam plates 225, which have the slot therein through which passes the shaft 196, and the cam portions 226 cooperate with the outer ends of the ratcheted disks 200 to throw them into the plane of the teeth 201 when the bar is thrown down. It will be noted that there is considerable lost motion between the cover plates 5% and the bar 55, so that the interlocking mechanism will be operated before the bar 55 is moved to cause the winding up of the roll, which is necessary to complete the casting of an irregular vote. In order to prevent mischievous persons from operating the bar 55 without having operated any of the free-ballot slides, I provide looking means to prevent the bars from being moved until the free-ballot slides have been moved far enough to operate the interlocking mechanism, so that it will be impossible to actuate the free-balloting mechanism maliciously without losing a vote on the regular'candidate keys. For this purpose, I pivot to the inside of the end pieces 30 and 31 the swinging hooks 227, the hooked lower ends of which cooperate with the pins 228 projecting inwardly from the bars 221. These hooks 227 are connected by a rod 229 passing through the apertures 280 in the end pieces 30 and 81, and extending across the machine in the plane of the cam offsets 231 30 party.

formed in the free-balloting plates The rod 229 is so located relative to the position of the cam surface 281 when the parts are unoperated that it will not be struck by said 5 cam surface until the interlocking mechanism has been operated. \Yhen it is struck by the cam surface during the downward movement of any of the free-balloting plates or covers, it will be seen that it will be swung to the rear so as to carry the hook 227 out of the plane of the pins 228 to allow the downward movement of the bar The extensions 202 are connected at their lower ends by the bar 232, which is conveniently constructed of an angle iron, the horizontal flanges of which are cut off at the ends so that the vertical flange can project through the slots formed in the end pieces 30 and 31. hen this bar is raised. when the machine is reset, if any of the free ballot plates have been moved, it engages the iiiwardly turned lower ends 23 1 thereof to reset them to normal position, and as they are reset, the members 210 are reset by the action 25 of the bar 71 and its cam slot 183.

be described. It is desirable to arrange the yes and no registers so that they can be used for persons of limited I" 'anchise, and to this end, I place outside of the sleeves 81, sleeves 235, which correspond in their general con- 40 struetion to the sleeves 81, except that they are enough larger to surround said sleeves. They have projections 236 corresponding to the projections 82 extending into the plane of the arms 83, and their lower ends are provided with the cam recesses 237, with which cooperate cam projections 239 formed on the top of the keys of this row. To bal ance the construction, there are preferably .two of these cam recesses 237 cooperating with two oppositely-disposed cam-projec tions 23S, and these are arranged so that when a key in this row is operated, the action of the cam projections on the cam surfaces will raise the sleeve 235. If the franchise-limiting mechanism is set to prevent the operation of these particular keys, the projections 236 Ill engage with the arms 83 before the registers are operated, so that the movement is ineffective. To prevent the simultaneous operation of the two registers of a pair, I provide on the rear of the sleeves the pins 239, which cooperate with the levers 2&0 pivoted between each pair of sleeves on the top of the plate 73, so

that but one of the keys of a pair can be operated. Of course, it will be understood that the front wall is provided with the strips 211, or some similar mechanism socured thereto to form the pockets in which the ballot strips 2-l2 upon which the names are printed can be inserted.

While I have herein shown and described a novel franchise-liiiiiting mechanism, I do not herein claim the same, as the generic subject-iiiatter thereof is claimed in my application No. 358,815, filed February 2, 1907, and the specific details are to be claimed in a subsequent application.

While I have herein shown and described a novel free-balloting mechanism, and likewise a novel mechanism for resetting the I'OglSt'GT-S to zero, I do not herein claim the same, but reserve the subjectanatter thereof for future applications.

While I have shown and described my invention as embodied in the form which I at present consider best adapted to carry out its purposes, it will be understood that it is capable of modifications, and that I do not desire to be limited in the interpretation of the following claims, except as may be necessitated by the state of the prior art.
